Detailed description of issue
I have a pdf document that has png image as content and a watermark.
When I view the pdf using the PDF.js Express viewer, the colors of image looks faded(refer to the left section of the attached image). However, when I open the same content in the browser’s built-in viewer, the colors appear more vibrant(refer to right section of the attached image).

Hello Saurav,
Thank you for contacting PDFJS forums.

Comparing the provided document with other Viewers like Adobe, I can confirm that the color saturation is expected. Please see the attached image.

Thank you for your response. Is there any way to enhance the color saturation while loading the document? As shown in the previous image, the text becomes unreadable.

Hi there,

You can change how the document is rasterized by using updateRasterizerOptions(), however keep in mind that the document coloring is expected. More information on the API can be found here: PDFJS Express WebViewer Class: Document

Kevin
